Question

Hey! I need help with this question.

Apply the properties of integer exponents to identify all of the expressions equivalent to 18.

a) 2-3

b) 23

c) 123

d) 22x 2-5

e) 2-2x 25

Answer 1

confusing question.
18 = 2(3^2) , no such expression in your choices

did you mean 1/8 ??
then 1/8 = 1/2^3 or 2^-3

I see a "2-3" , perhaps ..... ??

notice we show exponents using the ^ key
e.g. 5^3 is "five cubed"

Answer 2

What does it mean by '' explain how your results relate to the properties of integer exponent

Answer 3

a) 2^-3 Is equivalent to 1/8

b) 2^3 Is not equivalent

c) 1
---- This is equivalent to 1/8
2^3

d) 2^2 x 2^-5 Yes it is equivalent to 1/8

e) 2^-2 x 2^5 It is not equivalent to 1/8.

I hope this helped. :-)
